Hi All,

Saw this on one of the grc newsgroups...

Does this Microsoft patent cause trouble?

Here's the link to the document.

And here's the abstract from the top of it:

Technique which utilizes a probabilistic classifier to detect 
"junk" e-mail
by automatically updating a training and re-training the 
classifier based
on the updated training set


Abstract
A technique, specifically a method and apparatus that implements the
method, which through a probabilistic classifier (370) and, for a 
given
recipient, detects electronic mail (e-mail) messages, in an incoming
message stream, which that recipient is likely to consider "junk".
Specifically, the invention discriminates message content for that
recipient, through a probabilistic classifier (e.g., a support vector
machine) trained on prior content classifications. Through a resulting
quantitative probability measure, i.e., an output confidence level,
produced by the classifier for each message and subsequently compared
against a predefined threshold, that message is classified as 
either, e.g.,
spam or legitimate mail, and, e.g., then stored in a corresponding 
folder
(223, 227) for subsequent retrieval by and display to the 
recipient. Based
on the probability measure, the message can alternatively be 
classified
into one of a number of different folders, depicted in a pre-defined
visually distinctive manner or simply discarded in its entirety

Regards,

Rick
